This game is very, very easy and you will get every single achievement by just playing through one playthrough (there are 2 choices that don't matter), then doing 2 things real quick in the menu afterward.
To make it even easier for you, pop the battery out while holding
to fastforward and it will keep going without you needing to hold it in. Just put the batteries back in once you need to make a choice/the game ends.
So, start a new game. Hold down
to fast forward until you get to a first choice.
Choose whatever you want. Then, sim to the next choice.
Choose whatever you want. Then, sim to a third choice.
Choose whatever again and sim until the game ends.
